Novak Djokovic marked his return to action with a dominant 6-0 6-1 victory over Greece's Ioannis Xilas to put Serbia in control of the Davis Cup tie. 

The 24-time major winner was playing his first match since his US Open third-round defeat by Alexei Popyrin at Flushing Meadows a fortnight ago.

And Djokovic, who helped his nation win the Davis Cup in 2010, looked close to his best as he dropped just a single game, while converting five of the seven break points he forced.

Wrapping up a dominant victory in just 45 minutes, he put Serbia 2-0 to the good in the World Group I tie.

Elsewhere in that group, Casper Ruud helped Norway wrap up a 3-1 win over Portugal.

The three-time major finalist, who put his nation 2-1 to the good alongside Viktor Durasovic in the doubles rubber, was a 7-6 (7-3) 6-2 victor over Jaime Faria in their singles clash.

Later in the day, Argentina booked their place in the final eight after Maximo Gonzalez and Andres Molteni saw off Finland in the doubles decider.

Rafael Nadal says he cannot commit himself to future tournaments after his withdrawal from the Laver Cup.

Nadal shared news on Thursday that he would not make an appearance at the annual event in Berlin, stating that it would not be in the best interests of Team Europe if he were to participate.

The Spaniard was last in action playing doubles at the Paris Olympics with Carlos Alcaraz, and while he says he is in a good space mentally, he was not able to confirm when he would next make a professional appearance on a tennis court.

He said: "Mentally, I’m good, no problems. I'm at home enjoying other things, training as much as I can every day.

"No drama, obviously these are decisions [the Laver Cup withdrawal] that are being made, and this was a possibility - it's been a while without competing. There will be someone else who can do better.

"Right now I’m not in a position to put myself down for anything.

"I said [I would play] until the Olympics and then we would see, and I'm in that period of rest."

Nadal has endured a difficult 2024 so far, playing just 21 competitive singles matches with a record of 13-8.

He has only one grand slam victory to his name this year, beating Jack Draper in the Australian Open, but he lost in the first round of the French Open to eventual finalist Alexander Zverev.

Carlos Alcaraz has led Spain to the quarter-finals of the Davis Cup Finals after a straight-sets win over Ugo Humbert.

The 21-year-old needed just one hour and 21 minutes to cruise through with a 6-3 6-3 victory, hitting 21 winners to his opponent's 14 as he backed up Roberto Bautista's win earlier on.

Bautista had to come from behind to edge past Arthur Fils, beating him 2-6 7-5 6-3, and converting 40% of his break points, bettering the Frenchman's 27%.

Spain are through in Group B, but elsewhere in Group D, US Open semi-finalist Jack Draper's return was unable to inspire Great Britain to victory.

Dan Evans was beaten by Tomas Martin Etcheverry earlier on Friday before Draper's first match since New York ended in a straight-sets 7-6 (7-4) 7-5 defeat to Francisco Cerundolo.

Despite making fewer unforced errors than the Argentinian (23 to 39), the British number one struggled to find an edge, though Evans and Neal Skupski claimed a consolation win in the doubles to make it 2-1.

They sit second in the group, missing the chance to qualify for the last eight, and now needing a win against Canada, who have been in fine form so far.   

Felix Auger-Aliassime and Denis Shapovalov moved Canada to the brink of qualification in the Davis Cup Finals group stage, comfortably dispatching Finland in Manchester.

Shapovalov needed just an hour and 13 minutes to beat Eero Vasa 7-6 (7-2) 6-2, backing up his win against Argentine Francisco Cerundolo on Tuesday. 

The Canadian served five aces to his opponents' three, producing three love games in the final set to get his nation off to a flying start. 

Auger-Aliassime followed up Shapovalov's victory with another straight sets win, this time over Otto Virtanen, emerging a 6-2 6-3 victor. 

The world number 21 was dominant on serve throughout his 73-minute triumph, saving all three break points he faced and winning 86% of his first-serve points. 

Auger-Aliassime and Shapovalov then prevailed in the doubles against Harri Heliovaara and Virtanen in another straight sets win, putting them top of Group D without dropping a set against their opponents.

Rafael Nadal confirmed he will not participate in next month's Laver Cup, believing there are "other players who can help the team deliver the win" for Team Europe.

Nadal last played at the Paris Olympics alongside Carlos Alcaraz in the men's doubles, with the Spanish duo knocked out at the quarter-final stage at Roland Garros. 

The 38-year-old also competed in the singles but was hampered by a thigh problem in Paris and suffered a second-round loss to eventual gold medallist Novak Djokovic.

Nadal participated in the inaugural edition of the Laver Cup seven years ago, defeating Jack Sock to help Team Europe claim a 15-9 victory.

It is yet to be confirmed who will replace the 22-time grand slam champion in Berlin next month as captain Bjorn Borg now goes in search of adding to his star-studded line-up.

Alexander Zverev, Alcaraz, Daniil Medvedev, Casper Ruud and Stefanos Tsitsipas have already been confirmed as the participants to face Team World in Berlin. 

Nadal posted a statement on social media, saying that he was making the decision for the benefit of the team.

“I’m really disappointed to share that I won’t be able to compete at the Laver Cup in Berlin next week," Nadal said. 

"This is a team competition and to really support Team Europe, I need to do what’s best for them and at this moment there are other players who can help the team deliver the win.

"I have so many great, emotional memories from playing in the Laver Cup, and I was really looking forward to being with my teammates and with Bjorn in his final year as Captain.

"I wish Team Europe the very best of luck and will be cheering them on from afar.”

The news will accelerate speculation that retirement could be imminent for the Spaniard, who was unsure of his future following his exit from the Olympic Games.

Carlos Alcaraz got a stroke of luck as he helped Spain make a winning start to the Davis Cup Finals group-stage campaign against Czechia as Tomas Machac retired through injury.

The French Open and Wimbledon champion dropped the first set 6-7 (3-7), but rallied to finish the second 6-1, forcing a decider after getting two vital breaks.

However, Machac pulled up in the opening game of the third set with cramp and was unable to carry on after one hour and 41 minutes on the court.

It followed Roberto Bautista's flying start in their opening singles match in Group B as he cruised past Jiri Lehecka 7-6 (7-1) 6-4, with the Czech making 27 unforced errors as he failed to find an edge.

In the doubles, Alcaraz and Marcel Granollers then had to dig deep, coming from behind to beat Adam Pavlasek and Jakub Mensik in three sets to give Spain a 3-0 victory and take them top of the group. 

Meanwhile, Great Britain also made a bright start to their campaign in Group D, despite US Open semi-finalist Jack Draper sitting out.

Dan Evans got them started in Manchester with a hard-earned 7-6 (7-3) 6-2 victory over Eero Vasa of Finland, converting both of his break points in the second set.

Billy Harris followed that up with an impressive tournament debut, looking unflappable as he earned the hosts an unattainable lead with his 6-4 7-6 (7-4) win over Otto Virtanen.

Finland got themselves on the board in the doubles though, with Evans and Neal Skupski unable to get the better of Harri Heliovaara and Virtanen ensuring it was only a 2-1 loss. 

Elsewhere, the United States joined Germany at the top of Group C with their 3-0 win over Chile and Italy's Matteo Arnaldi held off a spirited Thiago Monteiro to put them in control against Brazil in Group A after Matteo Berrettini's earlier victory.

Felix Auger Aliassime and Denis Shapovalov helped Canada make a winning start to their Davis Cup Finals group-stage campaign, overcoming Argentina in Manchester.

Former Wimbledon semi-finalist Shapovalov got Canada off to a flier in the opening singles match of the Group D encounter, beating Francisco Cerundolo 7-5 6-3 in one hour and 37 minutes.

Cerundolo committed 51 unforced errors in a disjointed display, giving up back-to-back breaks early in the second set as the match slipped away from him after a competitive opener.

Not to be outdone, Auger Aliassime followed up Shapovalov's victory by beating Sebastian Baez 6-3 6-3, keeping his opponent under fierce pressure throughout and converting seven of the 12 break points he forced.

Doubles specialists Maximo Gonzalez and Andres Molteni then beat Shapovalov and Vasek Pospisil in three sets, but that was not enough to deny Canada victory.

Great Britain and Finland are the other two teams in Group D, with Jack Draper leading the hosts' bid to reach the knockout stages in Malaga later this year.

Andy Murray expected to miss playing tennis after putting his racket down for the final time last month but said retirement has been "the complete opposite" to what he anticipated.

Murray, who won three grand slam titles across a glittering 19-year career, saw his time on the court come to an end at Roland-Garros in the Paris Olympics.

The 37-year-old competed alongside Dan Evans in the men's doubles, reaching the quarter-finals of the competition to eventual bronze medallists Taylor Fritz and Tommy Paul. 

Murray withdrew from Wimbledon ahead of the Games after picking up a back injury against Jordan Thompson at the Queen's Club Championship, the latest of many injury setbacks towards the latter stages of his career.

"Since I've stopped, I feel really free and have got lots of time to do whatever it is I want," Murray told BBC Radio 4's Today programme.

"I can dedicate time to my children and have free time to play golf or go to the gym on my own terms.

"It is really nice and I didn't expect that. I was expecting to find retirement hard and be missing tennis a lot and wanting to get back on the tennis court on tour.

"So far it has been the complete opposite to what I was thinking."

The 37-year-old won his first grand slam in 2012 at the US Open before ending Britain's 77-year wait for a men's Wimbledon champion in 2013, winning it again in 2016.

During his career, Murray played 1,001 singles matches in his career, earning his landmark victory against Alexei Popyrin in three sets at Queen's.

After his injury in W14, the Scot vowed that the 2024 Olympic Games would be where his career ended, a competition he won two gold medals in 2012 and 2016.

While there was no perfect ending in the French capital, Murray revealed he was now spending some quality time with his family. 

"The thing that I always found difficult in recent years was that there was always a guilt associated with what I was doing," Murray said.

"If I was going away for a trip of like three to four weeks I would feel guilty leaving my children at home or being away from my wife for a long time with them, so missing the kids I found hard.

"But if I was at home with the kids then I was running around and spending a lot of my time on my feet after training.

"I was then thinking 'is this going to affect my training or performance the next day, should I have my feet up?' I found that stuff difficult over the last few years."

After triumphing at Flushing Meadows, Jannik Sinner feels the next generation of stars on the ATP Tour push each other on.

Sinner won his second grand slam title by beating Taylor Fritz 6-3 6-4 7-5 in the US Open final on Sunday.

The Italian became the third youngest player in the Open Era to win the title at the Cincinnati Open and Flushing Meadows during the same season after Andy Roddick (2003) and John McEnroe (1981).

He is the third youngest player during the Open Era to register a minimum of 23 wins in grand slam matches during a single season, older only than Pete Sampras (23-2, 1993) and Rafael Nadal (24-2, 2008).

And while Novak Djokovic is still going strong, Sinner and Carlos Alcaraz are spearheading a new generation of stars that are already living up to their potential.

"I feel like the new generation, we push each other," the world number one told ESPN after his win over 26-year-old Fritz.

"I always have players who are going to make me a better player, because there are going to be times where they beat me.

"Then you have to try to find a way how to win against certain players."

Alcaraz was among those to congratulate Sinner, with the Spaniard posting on his Instagram story after the final.

Fritz, meanwhile, became the second oldest American male in the Open Era to reach a maiden men's singles final at a grand slam, after MaliVai Washington (27 years 15 days) at Wimbledon in 1996.

He was looking to emulate Roddick's success from 2003, ending a 21-year wait for a homegrown champion at Flushing Meadows, but could not get over the line.

"There's obviously a lot of positives, and when I get some time to cool down then I'll be happy about the fact that I made it to the finals," reflected Fritz, who feels like he let fans down.

"But right now I'm pretty disappointed in just a lot of things on the court, how I played, how I hit certain shots. It sucks.

"And I'm not saying that it necessarily would have made a difference. I don't know if it would have, but I just would have liked to have played better and given myself a better chance. It's really disappointing right now.

"I feel like the fans obviously, American fans, been wanting a men's champion for a long time, and I'm pretty upset with how I played. I feel like, I don't know, I feel like I almost let a lot of people down."

Taylor Fritz said he was "sorry" he could not provide home victory in the US Open after losing in straight sets to world number one Jannik Sinner in the final.

It has been 21 years since an American claimed the US Open title when Andy Roddick won in straight sets in 2003 against Juan Carlos Ferrero.

Fritz became the first American to reach the final since Roddick lost to Roger Federer in 2006, after beating Frances Tiafoe in the semi-finals.

He also registered impressive victories against Alexander Zverev and Casper Ruud on his route to the final.

Yet he came up short against the reigning Australian Open champion, losing 6-3 6-4 7-5 in the final in front of a home crowd at Flushing Meadows.

"Thanks to the fans. Being an American at the US Open is incredible, feeling the love all week," said Fritz after the final.

"I know we've been waiting for a champion for a long time, so I'm sorry I couldn't get it done this time, but I'm going to keep working and, hopefully, the next time."

Fritz became the second-oldest American (26 years and 313 days) in the Open era to reach a maiden men's singles final at a grand slam.

"It's been an amazing two weeks and congrats to Jannik, he played a great match. It was really impressive, he was too good," he added.

Jannik Sinner is proud of his "incredible year" but is still targeting improvements despite picking up his second grand slam win at the US Open.

The Italian edged a tight contest in straight sets, claiming his maiden title at Flushing Meadows with a 6-3 6-4 7-5 victory over home favourite Taylor Fritz on Sunday.

In the process, the world number one became just the third player to win the title at the US Open men's singles after dropping his opening set at the event in the past five decades, after John McEnroe (1981) and Patrick Rafter (1998).

Sinner fell behind in the final set and had to dig deep to overcome Fritz's late fight, and said that his self-belief ultimately carried him over the line.

"I just went day by day. Believing in yourself is the most important," Sinner said in his on-court interview.

"I understood, especially in this tournament, how important the mental part is in sport.

"It's been an incredible year. So many big wins, starting off in Australia which gave me confidence until now.

"The work never stops. I know I can still improve. I can't wait for my continued process.

"I love tennis. I practice a lot for this kind of stage. I know how much work Taylor puts in. He's doing an amazing job and congrats to you and the whole team.

"It's so nice to see you on big stages like this, and I'm quite sure there will be many more. I wish you the best of luck for the future."

Just before the start of the US Open, Sinner was cleared following an investigation, having twice tested positive for a banned substance in March.

The 23-year-old was inadvertently contaminated by a low level of a metabolite of clostebol – a steroid that can be used to build muscle mass – by his physiotherapist, who had used an over-the-counter spray for a cut on his own hand before treating the player.

With many worried about how that would affect Sinner's focus in New York, he credited his team for helping him get through the tough period.

"This title for me means so much because the last period of my career was really not easy," Sinner added.

"My team and the people who are close to me have supported me every day. I'm very happy and proud to share this moment with my team."

Jannik Sinner clinched the US Open title with a gripping straight-sets victory over Taylor Fritz on Sunday.

The momentum ebbed and flowed in a tight contest, with Sinner claiming his maiden title at Flushing Meadows 6-3 6-4 7-5 in two hours and 17 minutes.

Sinner quietened the home crowd early, breaking Fritz's serve in the opening game, but it only motivated the American, who edged in front shortly after by winning three on the trot.

The reigning Australian Open champion responded in kind though, going one better with a four-game winning streak to get the first set in the bag.

The second set was a cagey affair, with the players matching each other stride for stride, neither willing to blink first.

With the chance to level the score at 5-5, Fritz started to wobble, making a couple of unforced errors in the final game as he lost his serve, giving himself a mountain to climb.

It looked like Fritz had shaken that off in the third set though, as he took the first three points, but Sinner held out, not losing his serve.

Yet it was Fritz who earned the first break, taking a 5-3 lead.

But Fritz again lost his rhythm at the crucial moment – Sinner won the final four games, his triumph confirmed as his opponent hit it into the net.

The Italian Job is complete

It has already been a banner year for Sinner, who won his maiden grand slam final, beating Daniil Medvedev to claim the Australian Open.

And he has stood firm in New York, when other favourites, like Carlos Alcaraz and Novak Djokovic, fell in the early rounds, adding to his superb record on the hard court.

Sinner is the second-youngest player to win the Australian Open and US Open men's singles title during the same season, after Jimmy Connors in 1974, during the Open Era.

Meanwhile, he is the third player to win the title at the US Open men's singles after dropping his opening set at the event in the past five decades after John McEnroe (1981) and Patrick Rafter (1998).

Following Aryna Sabalenka's victory on Saturday, two players have won the women's and men's singles titles at the Australian and US Open during the same season for the fifth time.

With two grand slam titles now in the bag, the world number one has proven just why he is worthy of that status.

Just out of reach

Fritz was not only playing in his first grand slam final, but he was the first American to reach the showpiece at the US Open since Andy Roddick in 2006.

Among players representing the United States, Fritz (26 years and 313 days) is the second oldest in the Open Era to reach a maiden men's singles final at a grand slam, after MaliVai Washington (27y 15d) at Wimbledon in 1996.

He was looking to emulate Roddick's success from 2003, ending a 21-year wait for a homegrown champion at Flushing Meadows.

Having already beaten high-ranking players like Alexander Zverev and Casper Ruud en route to the final, Fritz had proven he was no pushover, but the world number one proved a different type of test.

Fritz was just lacking that cutting edge at the key moments, as a major title slipped out of his reach, but there is nothing to say that he cannot come back even stronger next year. 

John McEnroe says "you never want to count Novak Djokovic out" despite his failure to win a grand slam in 2024.

Djokovic's last major triumph came at Flushing Meadows last year as he won his third grand slam of 2023, levelling Margaret Court's record of 24 titles.

And it looked like he would overtake that record this year, but he has struggled with injuries and a lack of form, meaning he will end a calendar year without a major title for the first time since 2017.

While he ended his wait for a gold medal at the Paris Olympics last month, he only reached one grand slam final, losing in straight sets to Carlos Alcaraz at Wimbledon.

He then suffered a shock early exit to Alexei Popyrin in the third round in New York, but McEnroe is convinced the Serb has what it takes to prove everybody wrong.

"You never want to count him out," McEnroe told Eurosport.

"This would certainly be the first time where you could say with some seriousness that you start to wonder if he's going to win again.

"How long can this guy keep motivated? Then he won the Olympic gold. I'm amazed that he's kept it [motivation] for this long.

"I'm sure to be surprised either way. If he doesn't win [a major], you would be like wow – he won three of the four last year. And now we're saying he'll never win it again. And then I would sort of be surprised in a way if he did, because of his age.

"That's what he's facing right now. It will be interesting to see if he's able to pull it off. But I do think he'll try to find that motivation to get number 25."

Aryna Sabalenka's US Open triumph is proof you should "never give up on your dream".

Sabalenka, who lost to Coco Gauff in last year's US Open final, got the monkey off her back when she defeated Jessica Pegula at Flushing Meadows on Saturday.

The Belarusian prevailed 7-5 7-5 from a thrilling encounter on Arthur Ashe Stadium, with Pegula having reeled off five straight games to take a 5-3 lead in the second set before Sabalenka turned the tables back in her favour.

After becoming just the fifth woman to win both hard-court grand slam titles in the same season, Sabalenka said: "Everything I'm thinking, I remember all those tough losses in the past here and it's going to sound easy but never give up on your dream and just keep trying, keep working hard.

"If you're really working hard sacrificing everything for your dream, you're going to get it one day.

"I'm just super proud of myself. I never say that but I'm super proud of myself, I'm super proud of my team that no matter what, which situation we were facing this season and in the past, we were able to go through it and get all those beautiful trophies.

"It's also very special place here, the US Open. That's why it's very special, because no matter what, every time I was coming back stronger, and I was learning, I never gave up on this dream, and it means a lot."

Sabalenka is the sixth defending runner-up to win the US Open title in the Open Era, after Chris Evert (1980), Martina Navratilova (1986), Steffi Graf (1988 and 1995), Justine Henin (2007) and Serena Williams (2002 and 2012).

And though Pegula was the home favourite, there was still plenty of support from the crowd for Sabalenka.

She added: "That's everything, let's be honest without them it wouldn't be me and I wouldn't exist and as I always say without me you guys wouldn't exist too so you're welcome!

"No, no, I love you guys. Your support is everything and you're my family and I cannot imagine my tennis life and my personal life without you. I love you guys, I don't say it often but I will say it loud, thank you for being you."

Jessica Pegula looked back on an "incredible month" after losing 7-5 7-5 to Aryna Sabalenka in the US Open final.

Pegula, the oldest American woman to reach her maiden grand slam final, fought back bravely in the second set on Saturday.

Ultimately, though, Sabalenka had too much, reeling off three straight games to win her third major title.

Pegula, who lost to Sabalenka in the final of the Cincinnati Open after winning the Canadian Open, could nevertheless look back on her achievements with pride.

She said: "It has been an incredible month for me.

"I had a tough start to the year but managed to turn it around. I didn't expect to be standing here and I'm grateful for the last few months of tennis and some incredible matches."

Pegula is the fifth player in the past decade to defeat three former women's major finalists en route to the US Open final. Each of the previous four went on to win the event – Flavia Pennetta (2015), Angelique Kerber (2016), Sloane Stephens (2017) and Coco Gauff (2023), however.

But Sabalenka proved just too strong, as the Belarusian became the fifth player during the Open Era to win both hard-court grand slams, after Monica Seles (1991,92), Steffi Graf (1988,89), Kerber (2016) and Martina Hingis (1997).

"I wish she would have at least let me get one set," quipped Pegula, who won five straight games to go from 3-0 down in the second set to 5-3 up.

"We had a tough match in Cincinnati a few weeks ago and she's one of the best in the world.

"She's super powerful and isn't going to give you anything, she can take the racquet out of your hand.

"I'm just glad I was able to stay in there and keep taking opportunities."
